Video for Lesson 3 of Idiosyncratic Introduction to J

Well at least it did not take as long to get the video for Lesson 3 up and running. I took a slightly different approach here and animated the actual lines of J to show how the calculations take place. This is pretty straightforward for lists/vectors but may become more complicated when 2 dimensional arguments are used in the next lesson. I may need to draw on my experience with some of the NuVoc videos … and then again I may come up with something different again.

As always, comments and suggestions are welcome.

Cheers, bob
